The verdict

Main runs at 173% of its industry's injury rate - more dangerous than the typical Assembly plants, heavy trucks, and buses on chassis of own manufacture workplace, earning a grade D.

Main: 5.7 TCR = 173% of Assembly plants, heavy trucks, and buses on chassis of own manufacture BLS 3.3 · 2y Form 300A (see methodology below)

Main safety composite

Main scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 22%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
